这是我开发ios应用程序的第一次经验.我正在尝试使用Facebook图形API发布一些数据.我不断收到以下错误:

This is my first experience of developing an ios app. I am trying to Post some data using Facebook graph api. I am constantly getting the following error:

The operation couldn’t be completed. (NSURLErrorDomain error 400.)

我找不到NSURLErrorDomain错误代码的描述.400错误代码是什么意思?

I cannot able to find the description of NSURLErrorDomain error codes. What does the 400 error code means ?

推荐答案

NSURLErrorDomain 错误代码在此处列出 developer.apple/documentation/foundation/1508628-url_loading_system_error_codes

The NSURLErrorDomain error codes are listed here developer.apple/documentation/foundation/1508628-url_loading_system_error_codes

但是， 400 只是http状态代码( www.w3/Protocols/HTTP/HTRESP.html )返回，这意味着您的请求有问题.

However, 400 is just the http status code (www.w3/Protocols/HTTP/HTRESP.html) being returned which means you've got something wrong with your request.
